Definitions

  • Fig. 7 shows the same parts now fully coupled as step C.
  • the male part has reached its final position.
  • By-pass valve 3 is now in its other seat and has now closed off the fluid passage at point G, which means that the fluid flow from the inner passage will only flow into the male inner passage.
  • the outer return passages are still connected together. Since there is no fluid circulation in the operating element (tool) of hydraulic rescue systems whilst not coupled, the male part attached to such an operating element (tool) does not require an integral by-pass valve. This principle allows the design of a less complicated and much more compact coaxial coupling and coupling system.
